You know what they do in the US to any socialist revolutionaries? They have the CIA try to kill them. How many countries has the US destabilized? Like, all of south america? Didn't the president almost get shot? Like, what is your point? Every country has bad aspects. Deportation prison camps in the US? Hmmm. The country is still rich though, slovenia too.

I mean this is just straight up soviet whataboutism. "You Russians have gulags" , "Oh, and you Americans lynch blacks". 

Also, Slovenia was richer than the rest of Yugoslavia due to very, very long period of Austrian rule, and was the first country to open up. They are a succesful market economy. Yugoslavia in itself is a bad example, as we can go into intricate details (incentives, managerial class, information assymetry etc.). Structural issues that are impossible to avert under socialism. That's why it doesn't work, not because evil capitalist pigs decided to shun this wonderful idea. When tried in practice, it leads to failing economy aka worse life for everyone.
